RAZOR-BLADE-STROTPING DEVICE.

Application filed June 14, 1917. Serial No. 174,813.

To all whom it may concern:

) 1t knmrn that I, Lane L. FUnA-N, a

citizen of the United States, residing at "llliet River Falls, in thecounty of Penq in'gton and State of Minnesota; have In- Wmtcd certainnew and .useful Improve ments in Razor-BladeStropping Devices, of

which the following is a specification. This invention relates toimprovements in razor blade stropping devices and has for its object toprovide traveling straps for strapping the blade.

Another object of the invention is to provide cylinders for rotating thestraps and means whereby the straps travel in a straight line forstropping razor blades.

A still further object of the invention is to provide a pair oftraveling straps for stropping the opposite sides of a razor blade incombination with means. for alternately 9 another.

With the .above and other objects in view I have invented the deviceillustrated in the accompanying drawings in which; a

Figure 1 is a top plan view of my invention, and,

Fig. 2 is a section taken on the line A-A of Fig. 1. y

Like reference"characters indicate like parts throughout the followingspecification and in the several views in the drawings in which 1 is acasing having alined bearing plates, 2 and 3 for supporting each of theshafts 4 and 5, upon which cylinders 6 and 7 are fixed. Mounted on thebottoms of the cylinders are gears 8 and 8" which mesh with one another,whereby the cylinders operate in unison. Rotatably' mounted on thecylinders are endless leather stropping belts 9 and 10 which are longerthan the clrcumference' of the cylinders and which are held.

taut by .rollers 11 and 12 supported upon brackets 13 and 13 and similarbrackets 14.

These brackets areeach provided with screw ends 15 operating through theWall 16 of the casing and controlled by nuts 17 and 18 iwhereby they maybeadjusted to the straps aiid locked in position. The rollers 11 and 12are in alinement withthe inner periph-.

eral portions 17 and 18 of the cylinders whereby said belts travel in astraight line for a desired distance between the cylinders forthe'purpose of grinding the opposite sides 19 and 20 of the razor blade21 which is held between said straightiportions 22 Specification ofLetters Patent. Patentd Jan. 15; 191 8. i

and 23 of said belts, in the blade support 7 ing bracket24= which ismounted upon arms 25 and 26 secured to-the wall 27 off'the casmg I'm thesame manner as said brackets 13-and14. Arm 25 has a bearingsleeve25 inwhich the bracket 32 maybe rocked or oscillatdd. Said arms 25 and 26 maybe ad usted relative to one another in order to hold said razor blade21in any desiredam gular stropping position.

The vblade supportin bracket 24: is provided with resilient- Walls 28and 29 between which the razor blade 21 is securely clamped whereby saidblade is held in proper position for stropping. The resilient clamp 30on the upper end of the member 24 holds the handle 31 of the razor, onthe bar 32 of the bracket. The blade supporting bracket 24 is perforatedto accommodate a rod 33 passing transversely therethrough, and this redis attached to theoppositeside's' of a" bow-shaped yoke 35 adapted toshift on oscillate, laterally and freely, the rod. 33"

passing through the opening in the bracket 24, and oscillating thebracket, 'as'will'be understood. The member 35 is held under tension bymeans of a sprin 36, one end of which is secured to the Wal- 2 7Pivotally mounted upon-the upper ends 37 and 38 of the cylinders'fi and7 are arms 39 and 40, which are controlled in their movements bystaplesl and'42'and which are held in normal positionby =means ofsprings 43 and it. These arms on every second rotation of the cylindersengage-first the one side 45 and then the other side 46 of theishifti'ngmember 35 and cause the same to shift the razor support 24 whereby theblade will first enga 'e one belt 22"land then the other belt 23.- n theshaft-5 is a pinion 47, operated by a pinion 48 on. the crank shaft=49which is operated by the crank handle 50, the rotation of said handlecausing the rotation of the cylinder 7,'th.e

gear 8 of which operates the gear swhich is fixed to and rotates thecylinder 6. :By means of the ac ion of the arms 39 and40 the razor bladeis al ernately shifted. from one of the stropping *h'elts to the otherin suitably successive movements, whereby the blade may bejproperlyl,sharpened.

It will of course be, understood that the razor supporting device 24 maybe adapted toany make ot-razor or safety razor blgdel 'ilg Having thusdescribedmy invention, that which I claim asnew and de ire to secure byLetters Patent is:

1. A blade sharpenin device comprising a pair of spaced, revo vingcylinders, an endless stropping belt on each cylinder, and a spacedguide roller for each belt, an oscillatable blade supporting devicelocated between the cylinders and means on each cylinder to oscillatesaid supporting device toward the other cylinder.

2. A blade sharpening device comprising a. pair of spaced, revolvingcylinders, an endlessstropping belt on each cylinder, and

' a spaced guide roller for each belt, an oscillatable blade supportingdevice located between the cylinders, and a resiliently supported arm oneach cylinder adapted to oscillate said supporting device toward theother e linder.

3. A blade sharpening device comprising a pairof spaced, revolvingcylinders, an endless stroppii'ig belt on each cylinder, and a spacedguide roller for each belt, an oscillatable blade support, anoscillatablc yoke operatively connected therewith, and a resilientlysupported arm on each cylinder adapted to oscillate said yoke andsupport toward the other cylinder.

4. The combination with a pair of parallel traveling stropping belts, ofan oscillateble, perforated blade support, an oscillateble yoke having aguide rod passing through sailil support, and means for oscillating saidyo e. 5. The combination with a pair of revolving cylinders, an endlessstropping belt on each 0 linder, and a spaced guide roller for each elt,of an oscillatable, perforated bracket having resilient blade claspi-ngWalls, a yoke having a transverse rod passed loosely through theperforated bracket, in ret aining spring attached to the yoke, and aresilient arm on each cylinder adapted to contact with the yoke tooscillate the yoketoward the other cylii'ider.

In testimony whereof I afliX my signature in the presence of twowitnesses.
